Description: • Thallus crustose, episubstratic, grey to pale greenish, continuous, rather thick, coarsely granular or warted, esorediate. Apothecia biatorine, 0.4-1.4 mm across, sessile and constricted at base, at first almost flat but soon convex and more or less globose, often confluent and tuberculate, pale yellow-orange to almost ivory-white, epruinose, the margin at first distinct and concolorous with or slightly paler than disc, but soon excluded. Proper exciple colourless to yellowish in upper part, 60-80 µm wide laterally; hymenium colourless, but often with diffuse streaks of a pale yellow pigment, 60-75 µm high; paraphyses 1.5-2 µm thick at base, more or less clavate, the apical cells up to 5 µm wide; subhymenium 35-55 μm high; hypothecium 120-240 μm high, colourless or pale yellow. Asci 8-spored, clavate, with a K/I+ blue apical dome penetrated by a narrow, K/I– apical cushion surrounded by a narrow, deeply K/I+ blue zone, the wall K/I- but surrounded by a I+ red-brown, K/I+ blue outer layer, the ocular chamber relatively small, Biatora-type. Ascospores (0-)3-septate, hyaline, ellipsoid to fusiform, straight, 12-22 x 4-7 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on bark, mosses and plant debris, more rarely directly on rock in upland areas with frequent fog. The species was frequently confused with other taxa and Italian material needs revision.
